UNIDENTIFIED FLYING OBJECTS- UFO
INTRODUCTION:
An Unidentified Flying Object, or UFO, is the popular term for any aerial phenomenon that cannot immediately be identified. Some definitions, such as the one used by the USAF, define a UFO as an object unable to be identified after scrutiny, while other definitions define an object as being a UFO from the time it is first reported as being unidentified, even though most subsequently become IFOs, Identified Flying Objects.
Reports of unidentified aerial phenomena date back to ancient times, but modern reports and the first official investigations began during World War II with sightings of so-called foo fighters by Allied airplane crews, and in 1946 with widespread sightings of European “ghost rockets“. UFO reports became even more common after the first widely publicized United States UFO sighting, by private pilot Kenneth Arnold in mid 1947. Hundreds of thousands of UFO reports have since been made worldwide.
Since its introduction the term has become heavily associated with flying saucers and alien spacecraft, though an object may be classified as a UFO independently of opinion as to its origins. Most military and civilian UFO investigations concluded that the majority of objects can be identified either directly, or by applying Occam’s Razor.
History:
Unusual aerial observations have been reported throughout history. Some were undoubtedly astronomical in nature: comets, bright meteors, one or more of the five planets which can be seen with the naked eye, planetary conjunctions, or atmospheric optical phenomena such as parhelia and lenticular clouds. An example is Halley’s Comet, which was recorded first by Chinese astronomers in 240 B.C. and possibly as early as 467 B.C.
Other historical reports seem to defy prosaic explanation, but assessing such accounts is difficult. Whatever their actual cause, such sightings throughout history were often treated as supernatural portents, angels, or other religious omens. Journalist Daniela Giordano says many Medieval-era depictions of unusual aerial objects are difficult to interpret, but claims some depicting airborne saucers and domed-saucer shapes are often strikingly similar to UFO reports from later centuries. Art historians, however, explain those objects as religious symbols, often represented in many other paintings of Middle-Age and Renaissance.
Shen Kuo (1031–1095), a Song Chinese government scholar-official and prolific polymath inventor and scholar, wrote a vivid passage in his Dream Pool Essays (1088) about an unidentified flying object. He recorded the testimony of eyewitnesses in 11th century Anhui and Jiangsu (especially in the city of Yangzhou), who stated that a flying object with opening doors would shine a blinding light from its interior (from an object shaped like a pearl) that would cast shadows from trees for ten miles in radius, and was able to take off at tremendous speeds.
In China, Ming Dynasty built Temple of Heaven looks like UFO, it near Inner Mongolia where was a excellent airborne ground for UFO, even Qing Dynasty‘s emperors must made ritual on the Temple of Heaven, and their crowns look likes the UFO.
Pre-modern reports:
Before the terms “flying saucer” and “UFO” were coined in the late 1940s, there were a number of reports of unidentified aerial phenomena in the West. These reports date from the mid-nineteenth to early twentieth century. They include:
- On January 25, 1878, The Denison Daily News wrote that local farmer John Martin had reported seeing a large, dark, circular flying object resembling a balloon flying “at wonderful speed.”
- On November 17, 1882, a UFO was observed by astronomer Edward Walter Maunder of the Greenwich Royal Observatory and some other European astronomers. Maunder in The Observatory reported “a strange celestial visitor” that was “disc-shaped”, “torpedo-shaped”, “spindle-shaped”, or “just like a Zeppelin” dirigible (as he described it in 1916).
- On February 28, 1904, there was a sighting by three crew members on the USS Supply 300 miles west of San Francisco, reported by Lt. Frank Schofield, later to become Commander-in-Chief of the Pacific Battle Fleet. Schofield wrote of three bright red egg-shaped and circular objects flying in echelon formation that approached beneath the cloud layer, then changed course and “soared” above the clouds, departing directly away from the earth after two to three minutes. The largest had an apparent size of about six suns.
- 1916 and 1926: the three oldest known pilot UFO sightings, of 1305 catalogued by NARCAP. On January 31, 1916, a UK pilot near Rochford reported a row of lights, like lighted windows on a railway carriage, that rose and disappeared. In January 1926, a pilot reported six “flying manhole covers” between Wichita, Kansas and Colorado Springs, Colorado. In late September 1926, an airmail pilot over Nevada was forced to land by a huge, wingless cylindrical object.
- On 5 August 1926, while traveling in the Humboldt Mountains of Tibet’s Kokonor region, Nicholas Roerich reported that members of his expedition saw “something big and shiny reflecting sun, like a huge oval moving at great speed”.
- In both the European and Japanese aerial theatres during World War II, “Foo-fighters” (balls of light and other shapes that followed aircraft) were reported by both Allied and Axis pilots.
- On February 25, 1942, the U.S. Army detected unidentified aircraft both visually and on radar over the Los Angeles, California region. No readily-apparent explanation was offered. The incident later became known as the Battle of Los Angeles, or the West coast air raid.
- In 1946, there were over 2000 reports of unidentified aircraft in the Scandinavian nations, along with isolated reports from France, Portugal, Italy and Greece, then referred to as “Russian hail”, and later as “ghost rockets“, because it was thought that these mysterious objects were Russian tests of captured German V1 or V2 rockets. Over 200 were tracked on radar and deemed to be “real physical objects” by the Swedish military.
The Kenneth Arnold sighting:
The post World War II UFO phase in the United States began with a reported sighting by American businessman Kenneth Arnold on June 24, 1947 while flying his private plane near Mount Rainier, Washington. He reported seeing nine brilliantly bright objects flying across the face of Rainier towards nearby Mount Adams at “an incredible speed”, which he “calculated” as at least 1200 miles per hour by timing their travel between Rainier and Adams.
His sighting subsequently received significant media and public attention. Arnold would later describe what he saw as being “flat like a pie pan” and as flying “like a saucer would if you skipped it across the water” and also said they were and “half-moon shaped, oval in front and convex in the rear. …they looked like a big flat disk.” (One, however, he would describe later as being almost crescent-shaped.) Arnold’s reported descriptions was widely reported upon and gave rise to the terms flying saucer and flying disk.[ Arnold’s sighting was followed in the next few weeks by hundreds of other reported sightings, mostly in the U.S., but in other countries as well.
After reports of the Arnold sighting hit the media, other cases began to be reported in increasing numbers. In one instance a United Airlines crew sighting of nine more disc-like objects over Idaho on the evening of July 4. At the time, this sighting was even more widely reported than Arnold’s and lent considerable credence to Arnold’s report.
American UFO researcher Ted Bloecher, in his comprehensive review of newspaper reports, found a sudden surge upwards in sightings on July 4, peaking on July 6–8. Bloecher noted that for the next few days most American newspapers were filled with front-page stories of the new “flying saucers” or “flying discs”. Reports began to tail off after July 8, when officials began issuing press statements on the Roswell UFO incident, in which they explained the debris as being that of a weather balloon.
Over several years in the 1960s, Bloecher (aided by physicist James E. McDonald) discovered 853 flying disc sightings that year from 140 newspapers from Canada, Washington D.C, and every U.S. state except Montana.
Ufology:
Ufology is a neologism describing the collective efforts of those who study UFO reports and associated evidence. While not all UFO researchers believe that all UFOs are necessarily extraterrestrial spacecraft, they do believe the area merits research and that the possibility of extraterrestrial spacecraft should be taken seriously.
Battelle Memorial Institute:
An Air Force study by Battelle Memorial Institute scientists from 1952–1955 of 3200 USAF cases found 22% were unknowns, and with the best cases, 33% remained unsolved. Similarly about 30% of the UFO cases studied by the 1969 USAF Condon Committee were deemed unsolved when reviewed by the American Institute of Aeronautics and Astronautics (AIAA). The official French government UFO scientific study (GEIPAN) from 1976 to 2004 listed about 13% of 5800 cases as detailed yet inexplicable (with 46% deemed to have definite or probable explanations and 41% having inadequate information).
UFO hypotheses:
There are different opinions about the UFO phenomenon. To account for unsolved UFO cases, several hypotheses have been proposed by both proponents and skeptics; a few examples are given below:
Among proponents, some of the more common explanations for UFOs are:
- The Extraterrestrial Visitation Hypothesis (ETH): That UFOs are alien spacecraft
- The Interdimensional Hypothesis: That UFOs are the results of objects crossing over from other dimensions
- The Paranormal/Occult Hypothesis
- The hypothesis that they are time machines or vehicles built in a future time.
- The man-made craft hypothesis: That UFOs are top secret Russian or American aircraft
Similarly, skeptics usually propose one of the following explanations:
- The Psychological-Social Hypothesis
- The unknown natural phenomena hypothesis, e.g. ball lightning, sprites
- The Meteorological hypothesis—Peter F Coleman advanced a meteorological theory that many UFOs or unexplained lights are actually instances of visible combustion of a fuel (e.g., natural gas) inside an atmospheric vortex. He has argued his case in his book, Great Balls of Fire–a unified theory. This vortex fireball theory was first published in Weather and later in the Journal of Scientific Exploration.
- The Earthquake lights/Tectonic Strain hypothesis
- The Autokinetic effect hypothesis.
Other skeptical arguments against UFOs include:
Most UFO sightings are transitory events and there is usually no opportunity for the repeat testing called for by the scientific method.
- Occam’s razor of hypothesis testing, since it is considered less incredible for the explanations to be the result of known scientifically verified phenomena rather than resulting from novel mechanisms (e.g. the extraterrestrial hypothesis).
Physical evidence:
Besides visual sightings, cases sometimes have indirect physical evidence, including many cases studied by the military and various government agencies of different countries. Indirect physical evidence would be data obtained from afar, such as radar contact and photographs. More direct physical evidence involves physical interactions with the environment at close range—Hynek’s “close encounter” or Vallee’s “Type-I” cases—which include “landing traces,” electromagnetic interference, and physiological/biological effects.
- Radar contact and tracking, sometimes from multiple sites. These are often considered among the best cases since they usually involve trained military personnel and control tower operators, simultaneous visual sightings, and aircraft intercepts. One such recent example were the mass sightings of large, silent, low-flying black triangles in 1989 and 1990 over Belgium, tracked by multiple NATO radar and jet interceptors, and investigated by Belgium’s military (included photographic evidence). Another famous case from 1986 was the JAL 1628 case over Alaska investigated by the FAA.
- Photographic evidence, including still photos, movie film, and video, including some in the infrared spectrum (rare).
- Recorded visual spectrograms
- Recorded gravimetric (example) and magnetic disturbances (extremely rare)
- Landing physical trace evidence, including ground impressions, burned and/or desiccated soil, burned and broken foliage, magnetic anomalies, increased radiation levels, and metallic traces. See, e.g. Height 611 UFO Incident or the 1964 Lonnie Zamora’s Socorro, New Mexico encounter, considered one of the most inexplicable of the USAF Project Blue Book cases). A well-known example from December 1980 was the USAF Rendlesham Forest Incident in England. Another less than two weeks later, in January 1981, occurred in Trans-en-Provence and was investigated by GEPAN, then France’s official government UFO-investigation agency. Project Blue Book head Edward J. Ruppelt described a classic 1952 CE2 case involving a patch of charred grass roots. Catalogs of several thousand such cases have been compiled, particularly by researcher Ted Phillips.
- Physiological effects on people and animals including temporary paralysis, skin burns and rashes, corneal burns, and symptoms superficially resembling radiation poisoning, such as the Cash-Landrum incident in 1980. One such case dates back to 1886, a Venezuelan incident reported in Scientific American magazine.
- So-called animal/cattle mutilation cases, that some feel are also part of the UFO phenomenon. Such cases can and have been analyzed using forensic science techniques.
- Biological effects on plants such as increased or decreased growth, germination effects on seeds, and blown-out stem nodes (usually associated with physical trace cases or crop circles)
- Electromagnetic interference (EM) effects, including stalled cars, power black-outs, radio/TV interference, magnetic compass deflections, and aircraft navigation, communication, and engine disruption. A list of over 30 such aircraft EM incidents was compiled by NASA scientist Dr. Richard F. Haines. A famous 1976 military case over Tehran, recorded in CIA and DIA classified documents, resulted in communication losses in multiple aircraft and weapons system failure in an F-4 Phantom II jet interceptor as it was about to fire a missile on one of the UFOs. This was also a radar/visual case.
- Remote radiation detection, some noted in FBI and CIA documents occurring over government nuclear installations at Los Alamos National Laboratory and Oak Ridge National Laboratory in 1950, also reported by Project Blue Book director Ed Ruppelt in his book.
- Actual hard physical evidence cases, such as 1957, Ubatuba, Brazil, magnesium fragments analyzed by the Brazilian government and in the Condon Report and by others. The 1964 Socorro/Lonnie Zamora incident also left metal traces, analyzed by NASA.
- Misc: Recorded electromagnetic emissions, such as microwaves detected in the well-known 1957 RB-47 surveillance aircraft case, which was also a visual and radar case; polarization rings observed around a UFO by a scientist, explained by Dr. James Harder as intense magnetic fields from the UFO causing the Faraday effect.
These various reported physical evidence cases have been studied by various scientist and engineers, both privately and in official governmental studies (such as Project Blue Book, the Condon Committee, and the French GEPAN/SEPRA). A comprehensive scientific review of physical evidence cases was carried out by the 1998 Sturrock UFO panel.
Reverse engineering:
Attempts have been made to reverse engineer the possible physics behind UFOs through analysis of both eyewitness reports and the physical evidence. Examples are former NASA and nuclear engineer James McCampbell in his book Ufology, NACA/NASA engineer Paul R. Hill in his book Unconventional Flying Objects, and German rocketry pioneer Hermann Oberth. Among subjects tackled by McCampbell, Hill, and Oberth was the question of how UFOs can fly at supersonic speeds without creating a sonic boom. McCampbell’s proposed solution of a microwave plasma parting the air in front of the craft is currently being researched by Dr. Leik Myrabo, Professor of Engineering Physics at the Rensselaer Polytechnic Institute as a possible advance in hypersonic flight. In contrast, Hill and Oberth believed UFOs utilize an as yet unknown anti-gravity field to accomplish the same thing as well as no propulsion and protection of occupants from the effects of high acceleration.
Famous cases:
- Bob White (UFO hunter) claims to have an alleged UFO artifact. The Maury Island Incident
- The Ummo affair, a decades-long series of detailed letters and documents allegedly from extraterrestrials. The total length of the documents is at least 1000 pages, and some estimate that further undiscovered documents may total nearly 4000 pages. A Jose Luis Jordan Pena came forward in the early nineties claiming responsibility for the phenomenon, and most consider there to be little reason to challenge his claims.
- George Adamski over the space of two decades made various claims about his meetings with telepathic aliens from nearby planets. He claimed that photographs of the far side of the moon taken by a Soviet orbital probe in 1959 were fake, and that there were cities, trees and snow-capped mountains on the far side of the moon.
- In 1987 Ed Walters perpetrated a hoax in Gulf Breeze, Florida. Walters claimed at first having seen a small UFO flying near his home, and then in a second incident seeing the same UFO and a small alien being standing by his back door after being alerted by his dog. Several photographs were taken of the craft, but none of the being. Three years later, in 1990, after the Walters family had moved, the new residents discovered a model of a UFO poorly hidden in the attic that bore an undeniable resemblance to the craft in Walters’ photographs. Various witnesses and detractors came forward after the local Pensacola newspaper printed a story about the discovered model, and some investigators now consider the sightings to be a hoax. In addition, a six-figure television miniseries and book deal were nearly struck with Walters.
- Warren William (Billy) Smith, A popular writer and confessed hoaxster.
Investigation/Responses:
Some studies show that after investigation, the majority of UFOs are usually identified (see identified flying object). For example, a 1979 study by Allan Hendry, a UFO researcher dedicated to find evidence for extraterrestrial life, found that up to 91.4% of the reports he investigated were either identifiable (91.4%) or could possibly be attributable (7.1%) to known artificial objects and natural phenomena. Hendry’s figure for unidentified cases is considerably lower than many official UFO studies such as Project Blue Book or the Condon Report which found unidentified cases made up 6% and 30% of reports respectively.
UFOs have been subject to various investigations over the years, varying widely in scope and scientific rigor. Governments or independent academics in the United States, Canada, the United Kingdom, France, Belgium, Sweden, Brazil, Mexico, Spain, and the Soviet Union are known to have investigated UFO reports at various times.
Among the best known government studies are Project Blue Book, previously Project Sign and Project Grudge, conducted by the United States Air Force from 1947 until 1969, the secret U.S. Army/Air Force Project Twinkle investigation into green fireballs (1948–1951), and Brazilian Air Force Operation Saucer (1977). Major civilian UFO groups in the U.S that have conducted extensive investigations were/are NICAP, APRO, MUFON, and CUFOS.
UFO categorization:
Some researchers recommend that observations be classified according to the features of the phenomenon or object that are reported or recorded. Typical categories include:
o Saucer, toy-top, or disk-shaped “craft” without visible or audible propulsion.
o Large triangular “craft” or triangular light pattern
o Cigar-shaped “craft” with lighted windows (Meteor fireballs are sometimes reported this way, but are very different phenomena).
o Other: chevrons, (equilateral) triangles, crescent, boomerangs, spheres (usually reported to be shining, glowing at night), domes, diamonds, shapeless black masses, eggs, pyramids and cylinders, classic “lights”.
UFOs in popular culture:
UFOs constitute a widespread international cultural phenomenon of the last half-century. Gallup polls rank UFOs near the top of lists for subjects of widespread recognition. In 1973, a survey found that 95 percent of the public reported having heard of UFOs, whereas only 92 percent had heard of US President Gerald Ford in a 1977 poll taken just nine months after he left the White House. (Bullard, 141) A 1996 Gallup poll reported that 71 percent of the United States population believed that the government was covering up information regarding UFOs. A 2002 Roper poll for the Sci Fi channel found similar results, but with more people believing UFOs were extraterrestrial craft. In that latest poll, 56 percent thought UFOs were real craft and 48 percent that aliens had visited the Earth. Again, about 70 percent felt the government was not sharing everything it knew about UFOs or extraterrestrial life. Another effect of the flying saucer type of UFO sightings has been Earth-made flying saucer craft in space fiction, for example the Earth-made craft Starship C-57D in Forbidden Planet, and the saucer part of the USS Enterprise in Star Trek.
